DIN Power Supply Benchtop Housing

This is a housing for a benchtop power supply using the "MingHe B3606" CC/CV module. There are several variants of this module, this is for the 36V/3A 50x66mm version.

If you have a hard time finding the module for purchase try a image search with Google Image or Google lens off the above picture of the module.

The design uses a Siemens SITOP PSU100S DIN Rail Power Supply as a DC source.
Other DIN supplies might fit as well. The dimensions of the used supply are: 70x126x126 mm.

There are three through holes for binding posts. I decided to use the 3rd to lead out the unregulated 24V/10A from the Siemens supply. Alternatively this position could be used for PE.

Printing
 

The print should be straight forward. Support is required at least for the front cutouts of the module as these need to be a precise fit.

The feet are ideally printed with TPU. An alternative that provides very good grip, is to cut pieces of silicone rubber hose and press them in.

The light-guides for the modules LEDs are not strictly necessary but make them less directional. Print with transparent PLA or translucent white.

For the raised lettering on the buttons I switched materials from black to grey during printing.

Materials
 

In addition to the printed pieces you will need:

• Three insulated binding posts.
• A switched and fused IEC socket and two screws to mount it.
• Two short M3 screws to fix the power supply module with the supplied frame to the housing. The screws that come with the module should work for this.
• Cabling.

Happy Printing!
